There is only 18" of clearance under the house. There are no drain lines anywhere around where the washer is going to be installed. The closest drain is to the bathroom sink, and it is roughly 15' away. The drain from the bathroom sink goes straight down into the ground.

SO, can someone give me an idea of how to connect the washer drain into the sink drain? I'd like to run the new drain in PVC, and tap into the cast drain. Can I get enough fall over 15', since there is only 18" of clearance?

Any help appreciated. Thanks
